Filed: 1935-03-21
Abstract: 450,609. Mop - wringing appliances. WATLING, H., Mid Tors, Dousland, near Yelverton, South Devon. March 21, 1935, No. 8839. [Class 19] A mop consists of a bag 7 of woven material or the like, through the bottom of which is laced a string 8, say, from the left hand corner to the right hand corner and back again, the length of the string being such that its ends extend beyond the left hand corner. A second string 8 is laced in like manner through the bottom of the bag from the right hand corner and a draw string 9 is laced through the mouth of the bag. The strings 8 are passed through holes 3 in a disc 2 at the bottom of a handle 1 and are drawn tight with the result that the mop material is puckered under the disc 2. The ends of the string are wound round the handle 1 between the disc 2 and a rubber ring 10 and are knotted together. The mop head is secured to a ribbed sleeve 4 on the handle by the draw string 9. Relative rotation of the handle 1 and member 4 wrings the mop.

The spot S on the screen may be made more visible by elongating it by applying a constant sinusoidal voltage to a second pair of electrodes at right angles to P1, P2, Fig. 4 (not shown). Fig. 5 shows a more complex system in which two pairs of transmitters E1, E2 and E3, E4 (each transmitting a different frequency) cooperate with two receivers R1, R2, the outputs of which are separated as in Fig. 3 and applied to two pairs of deflecting elements P1, P2 and P3, P4, the resulting position of the spot on the screen corresponding to the position of a point on a map determined by the position of the transmitters E1 ... E4, Fig. 6 (not shown). In order to give an indication or control when the spot on the screen corresponds to a given point on the map, the light from the particular spot on the screen may be directed to a photoelectric cell, Fig. 8 (not shown), or the electron beam itself may complete a circuit (a) through two crossed wires located in the tube, Fig. 9a (not shown), the circuit being effective only when current flows in both wires, or (b) through a single wire which is insulated except at one point, Fig. 9b (not shown), or (c) between two rods which are separated by a short gap, Fig. 9c (not shown).

Title: Improvements in Take-up or Winding Mechanism for Fabrics or the like.
IPC: D03D49/20
Filed: 1916-07-05
Abstract: 108,337. Triple Record Co., and Browning, W. H. July 5, 1916. Winding webs.-Relates to means for winding up approximately equal lengths of a band of fabric or the like on a drum notwithstanding the increasing number of windings of the fabric thereon, and comprises a drum positively rotated at each step of the feed to take up a portion of the band fed and a spring or weight urged wheel or disk adapted to be positively rotated against its spring or weight, and on release to be urged by the spring or weight to further rotate the drum in the positive direction to take up any remaining slack in the band. The winding-drum is mounted on the axle a of a ratchet wheel b which is rotated intermittently by a reciprocating arm d engaging an arm c<1> loose on the shaft a and carrying a pawl c operating the wheel b. On the same axle a is mounted a part disk g which is rotated counterclockwise by a reciprocating arm m engaging a pin n thereon simultaneously with the forward rotation of the disk b, an attached spring k being thus put in tension and a detent l preventing forward rotation of disk g until after a certain amount of the band has been wound on the drum, leaving a slack length still to be wound. When therefore the detent e is released by the arm m on its return, moving a slide o engaging therewith, the spring k rotates the disk p forward and by a pawl h thereon engaging the wheel b rotates the latter and with it the drum to wind up the slack. When the arm d has a greater total travel than that of the arm c<1>, a stop e may be provided adapted to engage a pin c<3> on the arm c' to arrest the movement of the latter under the impulse of its return spring c<2> at the desired position. A weighted or spring.operated detent f is provided to prevent any backward rotation of the ratchet b or shaft a.

Abstract: 793,301. Measuring ash content by means of radiation. COAL INDUSTRY (PATENTS), Ltd. April 1, 1955 [April 1, 1954], No. 9597/54. Class 40 (3). The ash content of coal dust 12 flowing through a tube 13 having thin windows of plastics material is determined by a beam of X-rays from a source 10 some of which pass through the sample and are detected by an ionization chamber 16 while others are reflected to a detector 18 such as a Geiger counter which also receives fluorescence from the iron particles. Detector 18 is a Geiger counter so chosen as to respond only to the fluorescent radiation produced by the iron or alternatively is provided with a diffracting crystal so that only the fluorescent radiation is directed on to it. Detector 17 then produces an output dependent on the ash content of the coal but falsified by the iron content while detector 18 produces an output dependent on the iron content. At the output lead 22 of amplifier 20 to which both these signals are fed is produced a signal indicative of ash content. The Specification states that the X-rays should be of a wavelength of less than 1.74 Š.

Title: Pressure fluid-actuated oscillators
IPC: A61M16/00
Filed: 1975-03-07
Abstract: 1533550 Fluid regulation PNEUPAC Ltd 18 Feb 1976 [7 March 1975] 9697/75 Heading G3H In a pressure-actuated oscillator, e.g. for lung ventilation equipment, of the type comprising a five-way valve A having a pressure inlet port a, exhaust ports b, c, and inlet/outlet ports 1, 2, the spool member of valve A is moved into its alternative end positions under the control of timing  valves B.C. The timing interval of valve B is  adjustable directly by a variable restrictor Br (to set the period of the inhalation phase) and the timing interval of valve C (exhalation phase) is automatically adjusted in consequence. With the spool of valve A positioned to provide the connections shown by full lines the exhaust port b is connected with the actuator of valve B through restrictor Br and with the patient P through a sonic flow restrictor D, and the inlet port a is connected with pressure-fluid actuator of valve C through fixed restrictor Cr. The latter causes a delay before the valve C is switched by a build-up of pressure from source S via port a. Once valve C switches it connects source S with pressure-fluid actuator P 2  of valve A to switch the latter into its position providing the dash-line connections. Thus the actuator of valve B and the patient are connected with the pressure of the source gas, e.g oxygen, air or anaesthetic, and the actuator of valve C is connected with exhaust port c. Capacitance E in the exhaust line from port c upstream of throttle T, allows a sudden decay in the pressure in actuator of valve C and causes the valve C to quickly switch to the actuator P 2  (full line connection), whereafter throttle T controls the rate of further pressure decay. When sufficient time has elapsed the valve B is switched to connect source S with actuator P 1  whereby the valve A is switched back to the position giving the full-line connections, and the cycle is repeated. The adjustment of the restrictor Br alters the time taken before the valve B switches which, in turn, alters the period over which the pressure in actuator of valve C is allowed to decay through throttle T. Thus the degree of decay of the pressure and consequently the period necessary for its subsequent build-up when the actuator of valve C is connected to source S, are automically adjusted by the direct adjustment of restrictor Br. The arrangement may be such that the adjustment can provide a 6:1 change in the inhalation phase with a 2:1 change in the exhalation phase. Capaciance H and throttle G function to ensure that the oscillator will produce adequate intervals in the pressure pulses to the patient even when valve B is set to produce very short duration pulses.
